Garment wash

Garment wash happens after the shirt is already cut, sewn, and labeled — the finished piece goes through an industrial washer, typically 20 to 40 minutes at 140°F to 160°F, sometimes with a mild detergent or softener added. That single cycle draws out most of the shrinkage cotton jersey would otherwise dump on a customer's first home wash, commonly 3% to 5% in length, and it relaxes the fibers enough to change how the fabric drapes and feels against skin.

Comfort Colors built its whole reputation on this step: a 6.1 oz ring-spun tee that ships garment-washed and pigment-dyed in one pass, which is why it feels broken-in straight out of the poly bag and why its size chart runs a touch looser than a same-size Bella+Canvas 3001 that skips the process. We size print placement off post-wash measurements on any garment-washed blank, because the shrink already happened at the mill instead of in the customer's laundry room.

Spec garment-washed stock for any run where fit after the first few washes matters more than fit on delivery day — team merch worn weekly, retail tees sitting on a shelf for months before selling. Skip it on flash-cure, one-and-done event shirts where nobody's washing the thing more than a handful of times before it's retired to a drawer.

Garment wash gets confused with garment dye constantly, since both run a finished shirt through a washer. Garment dyeing adds color during that cycle; garment washing doesn't have to touch color at all — a mill can shrink-finish an already-dyed or already-printed piece with plain water and heat, no dye bath involved.
